Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a floating mud sampler that is adapted to sample soft soil (floating mud) with a high water content from the seabed, lakes, and reclaimed areas.

(Prior Art) There are various known soft mud samplers that collect soft mud that does not have a very high moisture content, but all of them have a bottom lid that opens and closes in a bucket style with a bottom opening that is divided into two. The structure is complicated, and the sampler itself is heavy at about 5 kg, making it difficult to operate, and when trying to collect a sample with a high water content, there is a lot of leakage from the bottom opening when pulling up the sampler, making it unusable. It was hot.

(Purpose of the invention) The purpose of the invention is to eliminate the above-mentioned drawbacks and to obtain a floating mud sampler that can collect floating mud with a high water content.

(Structure of the invention) The floating mud sampler of the invention includes a cylindrical container having an upper end and a lower end opening, and an upper lid and a bottom that are pivotally supported on the cylindrical container so as to open and close the upper end opening and the lower end opening of the cylindrical container, respectively. a lid; a frame supported by the cylindrical container so as to be movable up and down relative to the cylindrical container; a connecting rope connecting the lower part of the frame and the bottom lid for opening and closing the bottom lid; A hook having a hook portion that supports a cylindrical container via a support rope, a rod portion that supports the frame via a support rope, a hanging rope that suspends the hook eccentrically, and a hook that rotates the hook. A weight is dropped along the suspension rope so as to collide with the hook to cause the suspension to move.

(Example of idea) Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the floating mud sampler of the present invention includes a cylindrical container 1 having an upper and lower opening.
, a frame 2 that is movable up and down relative to this cylindrical container 1, a hook 3 that supports these, a hanging rope 4 that suspends this hook 3, and this rope 4.
and a weight 5 which falls along the direction and collides with the hook 3.

The cylindrical container 1 has a double-split upper lid 6 pivotally supported on its upper edge so that it can be rotated upward from the cylindrical container 1 in a double-door pattern to open and close its upper end opening, and one end of which is pivoted to open and close its lower end opening. A single bottom lid 7 that is pivoted at one end of the lower end opening of the cylindrical container 1 and rotated downward from the cylindrical container 1, and a hanging lid 7 formed on the outside of the cylindrical container 1 near the upper end opening. the frame 2 has a flange 8, and the frame 2 has a flange 8;
a plurality of pillars 9 located on the outside, and an upper ring 1 for frame support that connects the upper parts of the pillars 9 to each other
0, a lower ring 11 connecting the lower parts to each other,
The frame 2 has a connecting rope 12 for opening and closing the bottom lid that connects the side surface of the lower ring 11 and the middle part of the bottom lid 7 of the cylindrical container 1. The bottom cover 7 is configured so that it does not fall out downward from the cylindrical container 1 by abutting against the bottom cover pivot, and is connected to the lower ring 11 by the connecting rope 12 in this abutting state. is constructed such that it hangs down and opens the lower end opening of the cylindrical container 1.

The hook 3 has a tip end hook portion 13 and a rod portion 14 connected to the hook portion 13, and the hanging rope 4 is connected to a portion of the rod portion 14 closer to the hook portion 13, that is, at an eccentric position. A support rope 15 connected to the hanging flange 8 is suspended from the hook portion 13, and a support rope 16 connected to the upper ring 10 of the frame 2 is suspended from the free end of the rod portion 14. When the weight 5 collides with the top of the hook 3 in the state shown in FIG. 13 and support rope 1
5 is configured to be disengaged.

Since the floating mud sampler of the present invention has the above-mentioned configuration, if the support rope 15 of the cylindrical container 1 is suspended from the hook part 13 of the hook 3 as shown in FIG.
The frame 2 is supported by a pivot of the bottom cover 7 of the cylindrical container 1, and a support rope 1 connects the upper ring 10 of the frame 2 and the free end of the rod portion 14 of the hook 3.
6 protrudes loosely, and the bottom cover 7 hangs down from its pivot portion to open the lower end opening of the cylindrical container 1.

In this state, the cylindrical container 1 is lowered into the floating mud while suspending the cylindrical container 1 and therefore the frame 2 by the hanging rope 4. During this descent, floating mud enters from the lower end opening of the cylindrical container 1 and exits from the upper end opening, so the upper lid 6
is left open upwards.

Next, when descending to a predetermined depth, if the weight 5 is allowed to fall along the hanging rope 4, the weight 5 will be attached to the hook 3.
Upon collision with the top surface, the hook 3 rotates clockwise in FIG. 1, and as shown in FIG. The frame 2 is now supported via the support rope 16. In this state, the cylindrical container 1 falls downward relative to the frame 2, but the connecting rope 12 is tensed and the bottom cover 7 rotates upward to engage with the lower end opening of the cylindrical container 1 and close it. It is securely closed and the cylindrical container 1 is prevented from falling in this position.

Therefore, after this, the hanging rope 4 can be pulled up to collect floating mud at a predetermined depth from inside the cylindrical container 1.

(Effects of the invention) As mentioned above, according to the floating mud sampler of the present invention, the bottom cover can be closed reliably, and when the sampler is pulled up, the upper lid is automatically closed by the action of the floating mud at the top, so it can be used at different depths. It is possible to easily and reliably collect floating mud at a predetermined depth without any floating mud being mixed in.
Its operation is simple, and the time required for collection is short, e.g.
The advantage is that it takes about 5 minutes to sample a 10m point.
